Stephen Elop took the stage to
open the Microsoft MWC 2015 event and right off the bat unveiled the Microsoft
Lumia 640. After a brief intermission for a Windows 10 demo, Elop came back to
unveil the larger Microsoft Lumia 640 XL.

Both phones will launch
Windows Phone 8.1, but Microsoft's intention is to bring them and other modern
Lumias to Windows 10.
